PHYS 431: PHYS 431

Uncover the fundamental base quantities of the SI system and test your knowledge with a quiz to identify which one is not considered a base quantity. Is it mass, length, energy, time, or are they all base quantities? Join us to find out!

Explore the physics behind an athlete's rope climb. Understand the relationship between power, force, and time, and how to calculate the minimum power output an athlete exerts. Witness the interplay of physics principles in evaluating athletic prowess.

Explore the relative strengths of two fundamental forces, the electromagnetic force and the gravitational force, in this enlightening physics tutorial. Learn about Coulomb's law and Newton's law of gravitation, and uncover the significant difference in their constants that makes the electromagnetic force much more powerful than gravity.

Explore the physics of a car's quick deceleration, including angular acceleration, revolutions, time, distance, initial velocity, and the realism of the scenario.

Discover the physics behind violin string tension and the angle-dependent force required when pushing it against the neck. Explore how the angle affects the force needed.
